We believe great content should go live without trade-offs.
So, we built the technology to do it.

An image of the Vindral sweet spot of quality, latency and sync. An image of the Vindral sweet spot of quality, latency and sync.

The sweet spot

Vindral is optimized for high-quality playout with exceptional resilience while maintaining ultra-low latency and synchronization among viewers.

This places Vindral in a sweet spot within the industry.

1. Quality

Vindral enables crystal-clear experiences with unmatched stability - for everyone.

Our adaptive bitrate algorithm combined with our fully configurable latency provide an unmatched resilience for live streams, allowing sub-second latency across the globe even in 4K resolution.

2. Synchronization

Vindral's synchronized playout ensures that content is delivered simultaneously to all devices, resulting in a consistent experience with minimal latency.

Unlike other technologies that may have varying latency across different devices or over time, Vindral maintains latency consistency within fractions of a second.

3. Latency

For any interactive application, latency is pivotal. Vindral keeps viewers on a known latency of your choice, which is guaranteed for all viewers, across devices.

The configurable latency ensures that your viewers get the experience that you choose. The most common configurations are set at sub-second glass-to-glass.

Configurable latency

Latency is a critical factor in live streaming. It refers to the delay between the time a signal is sent and when it is received by the viewer. For any interactive application, latency is pivotal, as it can greatly impact the user's experience.

At Vindral, viewers are kept on a known latency of your choice, which is guaranteed for all viewers, across devices. This means you have the flexibility to configure the latency to your needs, whether it's 700ms glass-to-glass or around one second. The configurable buffer ensures that all viewers get the same experience.

Vindral's most common configurations are set at sub-second glass-to-glass latency. This means that the delay between the source and the viewer is virtually imperceptible. Whether you are streaming live events, webinars, or delivering on-demand content, viewers will receive the experience intended, without any lag or delays.

Our SDKs provide support for configuring a static latency which can be set on a per channel basis, per region/country, or based on other parameters relevant to your use case.

Quality enabling in-depth details

From live sports to remote inspections, audiovisual quality is more important than ever. Vindral enables crystal-clear experiences with unmatched stability, even for viewers on congested networks. Achieving quality retention, especially at 4K, marks a significant advantage over real-time solutions such as WebRTC. Vindral's cutting-edge adaptive bitrate algorithm, together with the fully configurable latency, provide unmatched resilience for live streams - unlocking 4K sub-second latency across the globe.

Compared to solutions based on WebRTC technology, Vindral provides a more resilient stream; with smoother playback and higher image quality. On non-perfect networks, such as mobile and WiFi networks, competing technologies struggle in terms of frame drops, freeze frames or suffer display artifacts.

Below is a comparison video, from extensive - structured and automated - testing, for a leading WebRTC vendor.

1080p 4Mbps, baseline, GOP 1s

Network profile 4G (latency 97ms, jitter 12ms, packet loss 1.7%)

Synchronized playout

Playout sync is a crucial aspect of live video streaming, as it ensures that all viewers receive content simultaneously. With Vindral's synchronized functionality, no viewers are left behind. Content reaches all viewers at the same time, no matter their device or location, yielding a seamless and coherent experience at a guaranteed latency.

  • Viewers are on the same latency, regardless of device
  • Maximum of 100 ms drift (HLS: 20-40 s, LL-HLS: 2-8 s)
  • Coupled with ABR the stream is retained even on weak markets and networks
  • Works with our ultra-fast channel switching, bringing cutting-edge experiences to the next level.
  • The system decides what is played out, not the viewer device.

Retained quality. Guaranteed latency.

And no unwanted surprises. Blurry video, lag, and viewers falling behind make live streaming cluttered and messy. Poor live streaming experiences are not only frustrating but influence brands' ability to uphold high-quality recognition among their consumers. Powering a first-class presence, viewers can experience captivating moments exactly as they unfold, swiftly and in crisp quality.

A global live CDN

Vindral Live Streaming Service is available globally, ensuring accessibility in all regions. Core features across our service include ultra-low latency, playback synchronization, redundancy, and high availability.

Vindral utilizes global load balancers (GLBS) and redundant instances of all services, running on multiple ISPs, networks, and multiple data centers. The global load balancer service built into the Vindral CDN automatically chooses the closest available data center with available egress capacity. Utilizing several major ISP:s and Cloud Providers, including Tata Communications, GCP, Azure, Clouvider, OVH, Digital Ocean, Cloudflare, and Oracle, Vindral is set for global scalability.

Moreover, using traffic rules, we can ensure your streams are protected based on the viewer's location. As a result, all streams are GDPR compliant. At the core, Vindral is designed for automatic failover, traffic routing & optimization, and no single point of failure.
